METHOD OF PREPARING REFRIGERATING SALT.

Application filed October 17, 1923. Serial N o. 669,195.

This invention especially relates to the handling of refrigerating salt as used in making and preserving ice cream, the object of the invention being to place the salt on a carrying medium, such as a piece of paper or other suitable material so that the salt can be handled in a neatand convenient manner at soda fountains and other places where ice cream is sold. a

Another object of this invention resides in fixing a quantity of salt in sheets so the same will readily disintegrate upon submersion in a liquid.

This invention also consists in certain other features of construction and in the .combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed 'out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Fig. 1 is a face View of a sheet of paper with the salt applied thereto. Fig. 2 is a sectional View through the sheet.

In these views 1 indicates a sheet of paper, cardboard, or other suitable material, which is given a thin coating 2 of glue or other adhesive. Salt, shown at 3, is then sifted over the paper so that the salt will adhere thereto and thus a sheet containing a coating of saltis produced. This sheet can be very easily handled as it canbe wrapped around the package to be kept cool and then ice is packed around the wrapped package. By this invention the handling of ice cream salt greatly facilitated as it is not necessary for the hands to come in contact with the salt. The fountain can more easily be kept clean as there is no danger of spilling the salt in handling the same. I

In practicing this invention, it may be found more expedient to deposit the salt on a dissolvent sheet of material and the right is reserved to resort to the combination of applying refrigerating salt on a dissolvent l0 retaining sheet or binding the same by a dissolvent substance, such as' gelatine or other glutinous substances which are readily dissolved in kiguid. In forming an article of manufactui as set forth, the salt is preferably deposited in or on the carrying substance whenin a liquid state and upon becoming cool the glutinous or similar sub stance will cause the salt to. become fixed thereto. \Vhen the aforesaid is subjected to moisture or liquid the carrying substance will dissolve and deposit the salt where its refrigerating function is required.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall With- '70 in the scope of the appended claims.

What I claim is":

'1. A new article of manufacture in the form of a refrigerant medium comprising a sheet of flexible paper having grains of salt fixed'to one surface by a soluble substance.

2. A new article of manufacture in the form of a refrigerant medium comp'rising a sheet of paper having salt fixed thereon by a soluble substance.

In testimony whereof I affix my signature.
